kbuild: kill false positives from section mismatch warnings for powerpc

Building an allmodconfig kernel for ppc64 revealed a number of false
positives - originally reported by Andrew Morton.
This patch removes most if not all false positives for ppc64:

Section .opd
The .opd section contains function descriptors at least for ppc64.
So ignore it for .init.text (was ignored for .exit.text).
See description of function descriptors here:
http://www.linuxbase.org/spec/ELF/ppc64/PPC-elf64abi-1.7.html

Section .toc1
ppc64 places some static variables in .toc1 - ignore the.

Section __bug_tabe
BUG() and friends uses __bug_table. Ignore warnings from that section.

Module parameters are placed in .data.rel for ppc64, for adjust pattern to
match on section named .data*

Tested with gcc: 3.4.0 and binutils 2.15.90.0.3
